4. The display apparatus of claim 1 , further comprising a third straight portion that connects the first straight portion to the curved portion.
5. The display apparatus of claim 1 , further comprising an upper film disposed on the thin film encapsulation layer.
6. The display apparatus of claim 1 , wherein the thin film encapsulation layer comprises at least one organic film and at least one inorganic film.
7. The display apparatus of claim 1 , further comprising a pad unit disposed in the peripheral area, wherein the pad unit is disposed adjacent to the first straight portion or adjacent to the second straight portion.
8. The display apparatus of claim 1 , wherein the substrate comprises a straight portion and a curved portion, the straight and curved portions of the substrate corresponding to a shape of the thin film encapsulation layer.
9. The display apparatus of claim 1 , wherein the curved display unit comprises a plurality of pixels, and each of the plurality of pixels comprises at least one thin film transistor (TFT) and an organic light-emitting diode (OLED) that is electrically connected to the at least one TFT, wherein the OLED of each of the plurality of pixels comprises a pixel electrode, an organic light-emitting layer, and a common electrode.
10. The display apparatus of claim 1 , wherein the thin film encapsulation layer directly and fully covers the top surface of the curved display unit and four side surfaces of the curved display unit with the substrate directly and fully covering a bottom surface of the curved display unit, wherein the top surface of the curved display unit is a surface of the curved display unit from which an image is displayed.
11. A method of manufacturing a display apparatus, comprising:
providing a substrate including a circular display area and a peripheral area disposed around the circular display area;
forming a circular display unit in the circular display area;
forming a thin film encapsulation layer on the circular display unit, and sealing the circular display unit on the substrate with the thin film encapsulation layer; and
forming an upper film on the thin film encapsulation layer,
wherein, in plan view, an edge of the thin film encapsulation layer comprises a first straight portion, a second straight portion separated from the first straight portion, and a curved portion disposed between the first and second straight portions, and
wherein forming the upper film comprises attaching the upper film on the thin film encapsulation layer by using a roller, wherein using the roller comprises moving the roller on the upper film in a first direction, from the first straight portion towards the second straight portion of the thin film encapsulation layer, to press the upper film on the thin film encapsulation layer.
12. The method of claim 11 , wherein the first straight portion and the second straight portion are substantially parallel to each other.
13. The method of claim 11 , wherein the curved portion has a circular shape corresponding to a shape of the circular display unit.
14. The method of claim 11 , further comprising a third straight portion that connects the first straight portion to the curved portion.
15. The method of claim 11 , wherein the thin film encapsulation layer comprises at least one organic film and at least one inorganic film.
16. A display apparatus, comprising:
a substrate including a circular display area and a peripheral area disposed at a border of the circular display area;
a circular display unit disposed in the circular display area; and
a thin film encapsulation layer disposed on an entire top surface of the circular display unit,
wherein the circular display unit is disposed between the substrate and the thin film encapsulation layer,
wherein the circular display unit is encapsulated by the substrate and thin film encapsulation layer, and
wherein the thin film encapsulation layer includes at least two straight edges connected to each other by a curved edge.
17. The display apparatus of claim 16 , wherein the thin film encapsulating layer includes an organic film and an inorganic film stacked on one another.
